; We're really just checking for no crashes
; The feature we're testing for in AdjustWriteMask leaves the image_load as an instruction just post amdgpu-isel
; In reality, it's hard to get an image intrinsic into AdjustWriteMask with no uses as it will usually get removed
; first, but it can happen, hence the fix associated with this test
